M5.9 Earthquake 41 km SW of Sola, Vanuatu — May 28, 2025
2025-05-28 08:57:47 UTC (2025-05-28) · approx. 7:57 PM UTC+11 local
On May 28, 2025 at 08:57 UTC, a magnitude 5.9 intermediate depth earthquake struck 41 km SW of Sola, Vanuatu, at a depth of 190.0 km and coordinates -14.1835°, 167.3309°. The USGS PAGER system issued a green alert level for this event, indicating no significant casualties or damage expected. This earthquake was detected by 135 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 536, placing it among routine seismic activity. The nearest populated place is Saratamata (population 0).
Physical scale: An earthquake of magnitude 5.9 releases seismic energy equivalent to roughly 11 kilotons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 7.1 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Vanuatu, a region characterized by the New Hebrides subduction zone, where the Australian Plate subducts eastward at approximately 90 mm per year. View all earthquakes in Vanuatu.
